Part two (of four) of a series of volumes containing schemata that were to be discussed by the Fathers of the Second Vatican Council. This volume, containing two schemata, was distributed towards the end of the first session, and on 1st December 1962 they began to be discussed by the Council Fathers (see
Acta Synodalia, I.4,
passim, and
II.1, pp. 467 ff.).
While not officially part of the Acta Synodalia of the Second Vatican Council, these volumes are very much related to it.
